Surface Plate Ledges (Optional):
Product pricing below does not have ledges. Surface Plates without ledges (0-Ledge ) are the most commonly used and purchased 99 percent of the time for most manufacturing facilities. Ledges are for work clamping purposes only.  For 2 or 4 Ledge Surface Plates, contact us for pricing and availability.

Steel Support Stand (sold separately): See Granite Surface Plate Support Stands
Precision granite surface plates should never be placed on table-tops!
A steel support stand is required to use any granite surface plate. Three-point fixed suspension stands are recommended to minimize sag and warp, thus maximizing accuracy long term. Align the markings on the bottom of the granite plate with the supports on the stand.

Vinyl Covers (sold separately): See Granite Surface Plate Vinyl Covers
Purchase a Vinyl Cover to maintain accuracy and prevent wear due to abrasion of sliding parts on unclean surfaces.
